When you talk about investing in real estate of course it takes a lot of money, you can't invest real estate with small amount. so i think real estate investment are only for a big investor. Imagine if you are a big investor then you invest in altcoin i think you can earn more than real estate investment out there. More easy, more faster, more profit.
Sometimes digital assets are backed up by a real physical asset. For example, the cost of the token is emitted to the real estate area. A major investor is a subjective concept.
